Device and method for folding a flexible material web

Abstract

A device and a method are described for folding a flexible material web (1) using at least one pair of counterrotating laying rollers (2, 3), between which the material web may be fed to a folding location (4), the laying rollers (2, 3) being part of a laying carriage (5) which is movable over the folding length (L) of the material web (1) with reversible orientation. The object of the present invention is to guide the material web to the folding location with its position and composition largely unimpaired. This object is achieved in that the laying carriage (3) includes at least two transport bands (6, 7), which rotate around the laying rollers (2, 3) and set them into motion, the material web (1) is transportable at least partially guided between the transport bands (6, 7), and the speed of the material web (1) has the same absolute value as the speed of the transport bands (6, 7).

Dependencies are inferred from the claim text.
